A 45 g mass is attached to a massless spring and allowed to oscillate around an equilibrium according to:
y(t) = 1.3 * sin( 0.6 * t ) where y is measured in meters and t in seconds.
(a) What is the spring constant in N/m?
k = N/m
HELP: You are given m, the mass. What other quantity appears in the equation involving k, the spring constant, and m?
HELP: You are given the equation of motion
y(t) = A * sin( ω * t )
Now can you find the missing quantity?
HELP: Be careful of the units of m.
